ʻO ka papa 8.8 ʻo nā kī kīwī wela ka ikaika kiʻekiʻe.Ke hoʻohālikelike ʻia me nā bolts maʻamau, e hoʻomaikaʻi ʻia ka ikaika tensile o nā bolts kiʻekiʻe.
Hoʻohana ʻia ʻo Hot dip galvanized hexagon bolt e hana i ka hoʻoheheʻe metala me ka hao matrix e hana ai i ka papa alloy, i mea e hoʻohui ai i ka matrix a me ka uhi.
ʻO ka galvanizing wela e pili ana i ka pickling o nā ʻāpana hao a me ke kila.I mea e wehe ai i ka hao oxide ma ka ʻili o ka hao a me nā ʻāpana kila, ma hope o ka pickling, hoʻomaʻemaʻe ʻia lākou i loko o ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia i ka pahu wai wai, a laila hoʻouna ʻia i ka pahu wela wela.
Loaʻa i ka bolt hexagon heat-dip galvanized ka maikaʻi o ka uhi ʻana, ka hoʻopili ikaika, ka wai a me ke ola lawelawe lōʻihi.
